IMPROVEMENT IN PRINTERS SIDE-STICKS AND QUOINS.

Specification forming part of Letters Patent No. 145,574, dated December16, 1873; application filed November 8, 1873.

To all whom 'it may concern.:

Be it known that I, FRANoIs KEEIIN, of Milwaukee, in the county ofMilwaukee and State of Visconsin, have invented a new and usefulImprovement in Printers Side Sticks and Quoins, of which the followingis a spec-incation In the accompanying drawing, Figure l represents atop view of my improved side-sticks and quoins for locking printersforms; and Fig. 2 a vert-ical vtran sverse section of the same on theline c c, Fig. 1.

Similar letters of refe-rence indicate corresponding parts.

The object of myinvention is to furnish, for the use of printers, animproved side-stick and vquoins, by which theforms may be easily setwithout injuring` theimposing-stone, and firmly retained during theprinting process. My invention consists in constructing the sidestickwith wedge-shaped sections, which are wider at the base, forming aprojecting step, along which the wedge-shaped quoins, with asimilarly-projecting top step, are guided, so as to contine the type 1nthe chase.

In the drawing, A represents the side-stick, and B the quoins, which areeither made of malleable iron, or cut from bar-iron with rotary cutters,or pressed in suitable dies, as maybe found most convenient. Theside-stick A is made of alternately wedge-shaped sections, as indicatedin Fig. l,and produced with a wider base, which projects, in the shapeofa step, A, about midway on the outer side of the same. The quoins Bare also produced in wedge-shape, of suitable size, with a topprojecting step, B', which is placed on step A', and driven along thesame to lock the types in the chase. p

The shape of the steps, and the width of sidestick and quoins,correspond exactly in size, so that the quoins may be rmly driven inposition on the side-stick without injuring the imposing-stone. Thequoins are even with the top of the side-stick, and allow the side-stickto be made of the same height as the chase. The wedge shape ofside-stick and quoins admits the rapid locking and separating of thetype, and the rigid retention of the same during printing.

Having thus described my invention, I claim as new and desire tosecure'by Letters Patentl. A printers side-stick, produced withalternatin g wedge-shaped sections and proj ecting base-step,substantially as described.

2. A quoin for locking the side-stick to the forms, being of equalheight with the sidestick, and of wedge shape, with a projecting topstep, as specied.
